The March 1875 Southeast tornado outbreak was a deadly tornado outbreak that affected portions of the Southern United States from March 19–20, 1875. At least 19 tornadoes were recorded, including seven that were destructive enough to be rated F4 by Thomas P. Grazulis. The worst damage and most of the deaths occurred in Georgia. Most of the damage appears to have been the result of two tornado families that moved along parallel paths 12 to 15 mi (19 to 24 km) apart through parts of Georgia and South Carolina. These families each consisted of numerous long-tracked, intense tornadoes. The deadliest tornado of the outbreak was an estimated F4 that killed 28–42 people in and near Sparta, Georgia, and Edgefield, South Carolina, on March 20. A separate F4 that followed a similar trajectory may have killed as many as 30. In all, this outbreak killed at least 96 people, injured at least 377, and caused at least $650,000 in losses.^{[1][nb 1][nb 2][nb 3]}

The ratings for these tornadoes were done by tornado expert Thomas P. Grazulis and are not official ratings.

• Note: Some of the events listed as individual tornadoes were probably tornado families.^[1]

A large F4 tornado tore a damage path 75 miles (121 km) long ranging from 300 yards (270 m) to over 1 mile (1.6 km) wide across portions of Georgia and South Carolina. The tornado caused its first damage northwest of Sparta, Georgia, in Hancock County, after which it destroyed dozens of farms. Four people were killed in Hancock county, three of them on one farm. A door hinge from the farmhouse was found embedded 3 inches (7.6 cm) deep in a tree more than 1⁄4 mi (0.40 km) away. At least six people died in Warren County, including one at a church west of Warrentown. The pastor attributed the survival of the majority in the church to the pews, which stopped some of the falling timbers. The tornado then moved through Camak, where 39 of the town's 40 homes were damaged or destroyed. At least seven people, possibly as many as nine, were killed in McDuffie County, most of them in small cabins. The death toll in Columbia County may have been as high as 20, though only eight deaths were confirmed. At least four people died in Appling, and as many as eight may have died on a plantation. The tornado then crossed the state line into Edgefield County, South Carolina where damage was less severe. Here, six farms and plantations were destroyed with three fatalities. The tornado finally dissipated south of Edgefield. The death toll from this tornado is listed at 28, but due to uncertainties, it may have been as high as 42.^[13]
